Abstract: A method comprises receiving a kernel used to convolve with an input tensor. For a first dimension of the kernel, a square block of values for each single dimensional vector of the kernel that includes all rotations of that single dimensional vector is generated. For each additional dimension of the kernel, group blocks of an immediately preceding dimension into sets of blocks, each set of blocks including blocks of the immediately preceding dimension that are aligned along a vector that is parallel to the axis of the dimension; and generate, for the additional dimension, one or more blocks of values, each block including all rotations of blocks within each of the sets of blocks of the immediately preceding dimension. The block of values corresponding to the last dimension in the additional dimensions of the kernel is output as the expanded kernel.

Abstract: Applicant discloses a novel method of spray applying multiple courses of a rapid cure, two part polymer sealant to an aircraft surface. The method sometimes uses a two part polymer mix for use in the aircraft industry that is applied with pneumatic mix and spray gun. The two part cartridge is used in the mix and spray gun so the mix is applied immediately upon mixing, but the two components are kept separated unless the gun is applying the mix. The multiple courses cure to form a clear sealant that allows for inspection of cracks and corrosion beneath the sealant. It cures quickly so that the coated part may be further processed, for example in the assembly line during aircraft build. Applicant further discloses multiple spray gun systems for applying such a two-part polymer mix to aircraft parts.

Abstract: A closeable sealant wrap for placement about a workpiece includes a skin with a surface having a body dimensioned similar to the skin but narrower in width. Various closure means are deployed at one or more perimeter portions of the skin. The closure means may for example be a zipper which allows the sealant wrap to be enclosed around a wire, a fiber or a bundle of wires or fibers. The skin may be porous or non-porous. The body is a non-hardening, tacky polymer.

Abstract: An exercise machine that automatically adjusts one or more controls or settings based on a user's progression within a gaming environment is described. For example, the exercise machine, in response to the user (or an avatar representing the user) traversing a certain section or target area, can modify its operation (e.g., can initiate an auto-follow behavior or auto-adjust mode of operation) in sync with and/or in response to the user's movement or actions within the gaming environment.

Abstract: An assembly to provide a moisture proof or moisture resistant seal about a bundle of wires. The assembly includes a shrink boot, such as a cold shrink boot, and a tacky sealant, such as a polyurethane gel, that will deform and flow under the pressure of a collapsing tube of the shrink boot.

Abstract: A number of tacky polyurethane or other gel comprising composites are provided. The composites have foam carriers, which may be open cell, semi-open cell, reticulated or closed-cell foam. The tacky gel which, in one embodiment, may be polyurethane, typically comprising a thin surface coating on the foam gel and the foam is partially or fully saturated with the same gel comprising the thin surface layer of the foam. The skeletons may be included in the composite to provide additional structure integrity, and a moisture proof layer may be added to the top and/or bottom surfaces of the foam/gel.

Abstract: A number of sealants are provided that are resistant to degradation by aircraft fluids. In some embodiments, the sealants are resistant to degradation by Jet A fluid and at least one of the three types of hydraulic fluids typically used in aircraft. These embodiments are also typically cure in place from a two-part polyurethane or polyurea mix, with cure to a visibly clear coating. In some embodiments, they may be sprayed on an aircraft surface or applied by hand (brush or injectable). In other of these embodiments, the sealants comprise, at least in part, a cured, soft, tacky polyurethane gel that is resistant to at least one of a synthetic hydrocarbon based or mineral oil based hydraulic fluid. In one embodiment, the sealant is used on a blade type aircraft antenna.

Abstract: A method comprises receiving a kernel used to convolve with an input tensor. For a first dimension of the kernel, a square block of values for each single dimensional vector of the kernel that includes all rotations of that single dimensional vector is generated. For each additional dimension of the kernel, group blocks of an immediately preceding dimension into sets of blocks, each set of blocks including blocks of the immediately preceding dimension that are aligned along a vector that is parallel to the axis of the dimension; and generate, for the additional dimension, one or more blocks of values, each block including all rotations of blocks within each of the sets of blocks of the immediately preceding dimension. The block of values corresponding to the last dimension in the additional dimensions of the kernel is output as the expanded kernel.

Abstract: Gaskets, including aircraft gaskets, are disclosed, the gaskets having an elastomeric gel body and substantially incompressible skeletons. The bodies may be pliable and deformable and, in one example, may be comprised of a two-part chemically cured polyurethane that sets up as a gel after mixing with the web so that it is fully integral with the web and so that there is substantially no air bubbles or air pockets left in the web. The web may be a regular shaped web and made of nylon.

Abstract: Fireworthy sealants may have a variety of compositions and be made by a variety of techniques. In certain implementations, a fireworthy sealant may include a body comprised of a cured, tacky, soft, deformable non-adhesive gel. The gel body may have an upper surface, a lower surface, and a perimeter, wherein the upper and lower surfaces of the gel body, in an uncompressed state, define a body thickness. The sealant may, in an uncompressed state, be dimensioned to fit in a first opening between a wall and an aircraft component surface and deformable when under compression to fit in a second opening, smaller than the first opening. The sealant may be flame retardant and produce low smoke density and low smoke toxicity.

Abstract: A chemical composition comprising a mixture of a non-curing organic polymer base with a viscosity between 300 and 10,000 centipoises at 20 degrees C.° and a molecular weight of between 1,000 and 100,000. Into the base is mixed at least one of: metal particles (coated or uncoated), inert particles and non-metal corrosion inhibitors such that reaches a viscosity of between 9,000 and 10,000,000 centipoises. The result is a paste that is useful in applying to metal aircraft parts to help prevent corrosion, including galvanic corrosion.

Abstract: A method comprises accessing a flattened input stream that includes a set of parallel vectors representing a set of input values of a kernel-sized tile of an input tensor that is to be convolved with a kernel. An expanded kernel is received that is generated by permuting values from the kernel. A control pattern is received that includes a set of vectors each corresponding to the output value position for the kernel-sized tile of the output and indicating a vector of the flattened input stream to access input values. The method further comprises generating, for each output position of each kernel-sized tile of the output, a dot product between a first vector that includes values of the flattened input stream as selected by the control pattern, and a second vector corresponding to a vector in the expanded kernel corresponding to the output position.
